I'm attempting to install lsb-core on an Ubuntu server. Did apt-get update then did apt-get install lsb-core

root@quackwall:~# apt-get install lsb-core

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
lsb-core : Depends: lsb-invalid-mta but it is not going to be installed or
mail-transport-agent
Depends: binutils but it is not going to be installed
Depends: libc6-dev but it is not going to be installed or
libc-dev
Depends: cups-bsd but it is not going to be installed or
lpr
Depends: lprng or
cups-client but it is not going to be installed
Depends: m4 but it is not going to be installed
Depends: mailx or
mailutils but it is not going to be installed
Depends: make but it is not going to be installed
Depends: ncurses-term but it is not going to be installed
Depends: pax but it is not going to be installed
Depends: alien (>= 8.36) but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

So apparently Ubuntu doesn't feel like installing lsb-core. The one thing I can find on Google says that there mirror was out of date. However I can't find whats wrong with my sources.list. Below is a copy of it

Now I'm not entirely sure if that's good or not, but I know that I can run basic updates just fine. And since I'm using the US mirror, it shouldn't be out of date
